When fucking a girl in the vagina, and you in one sly, dastardly, and courageous movement you remove the penis from the vagina, and instantly slip it into her asshole.

When you get jumped from behind by a chump who wasn't brave enough (or good) enough to square up to you. So they gotta be a chump and jump you so you have no warning or defense.
CHUMP-JUMP
CHUMP-JUMP
There's no warning or defense when you get chump-jumped from behind, that's what makes them a chump. Next time square up CHUMP if you want a W.
